Hi,
I am staying in South Africa. I have a Kent Mango tree and it is now six years old. It had a good crop this year, but all my mangoes is small! They don't measure more than 10 cm (4 inches). Our summers is hot - 38 degrees C (100F). I water the tree once a week heavily (I've got a basin around the tree which I fill up). I give fertilizer every month from the blooming stage. I don't prune the tree. The tree seems healthy. Why don't I get huge mangoes?
